Undiscovered Country Anomolies

ugh sorry i deleted my post because I wanted to rephrase it but yeh, Hoshi is there as a science specialist. With Uhura I'm not sure, since I've not watched much TOS, what her expertise is other than Open Hailing Frequencies (which doesn't in of itself seem to require a comissioned officer). But I had always assumed it was more of an engineering role, like fixing and maintaining the Space Radios.

I think you are right, in at least one episode she is fixing the subspace radio with spock.

I deleted my quote of your previous post!

Definitely, Uhura's is a technical role, managing internal and external comns and maintaining the communications systems.

She's also proficient in other bridge duties such as navigation, and joins landing parties for more general roles - e.g. leading a search team looking for Bones in COTEOF.
